What’s in it for me? Use medieval wisdom to understand your flaws and live with more self-compassion.

Most of us think of the seven deadly sins as relics of medieval religion – maybe a little dramatic, maybe even a little comic. But for medieval thinkers, they were something far more practical: a map of the mind. Pride, envy, anger, sloth, avarice, gluttony, and lust were ways of naming the habits that pull you away from other people, from reality, and from yourself.

What makes this old system surprisingly useful is that it doesn’t treat human weakness as strange or shameful. It assumes that everyone struggles with thoughts and feelings that aren’t always constructive. The goal is to notice what’s happening inside you before it starts making your choices for you.

In this Blink, you’ll learn how medieval ideas about the seven deadly sins can help you understand ego, comparison, rage, despair, money, appetite, and desire with more honesty and compassion.

Let’s begin with the sin medieval thinkers feared most: pride.

Pride becomes harmful when confidence blocks connection

Pride can sound like one of the healthier emotions. You can be proud of work well done, proud of someone you love, proud of a part of yourself you once hid or doubted. Medieval thinkers were interested in a more dangerous version. They saw pride, or superbia in Latin, as the moment self-belief drifts away from reality and starts treating other people as obstacles, audiences, or tools.

The danger begins with a mistaken idea of your own importance. You decide you’re a little more gifted, a little more exempt, a little less in need of help than everyone around you. From there, the pattern hardens. Rules start to feel optional. Advice sounds insulting. Criticism becomes something to defeat rather than understand. At its worst, pride makes you stop seeing other people clearly, because your attention is fixed on protecting a flattering picture of yourself.

That’s why medieval artists returned to Lucifer so often. Before his fall, he could appear radiant, intelligent, and powerful – surrounded by signs of rank that made him seem higher than those around him. He was beautiful, and that made his pride seductive before its damage was visible. Beauty, ability, and ambition can become spoiled when they turn inward and refuse responsibility. Lucifer’s failure was choosing display over goodness, status over service, and separation over shared life.

This makes pride easier to recognize in ordinary life. It can show up as the need to seem special, the habit of bending rules for your own comfort, the urge to dominate a conversation, or the refusal to cooperate because dependence feels beneath you. Medieval writers weren’t asking you to hate yourself. After all, healthy pride can be an honest pleasure! The problem begins when your image of yourself grows larger than your actual life.

So, what’s the remedy? It’s accurate self-knowledge: see what you have, see what you lack, and let other people matter.

Now let’s look at envy, where the gaze turns outward and becomes just as dangerous.

Envy turns attention into resentment

Comparison can begin innocently enough. You notice another person’s success, measure it against your own life, and feel a pinch of unfairness. Medieval envy, or invidia, begins there but moves in a harsher direction. It doesn’t merely want the same good thing; it wants the other person’s good to be reduced, spoiled, or taken away.

That’s why medieval artists often pictured envy as a sickness affecting your ability to see and speak. In Giotto’s image of Invidia in the Arena Chapel, the figure’s damaged eyes, animal features, clutching hand, and serpent-like imagery turn envy into a whole-body disorder. The idea is clear: envy changes how you look at others. Their happiness starts to feel like an accusation. Their gifts become threats. Their flaws become strangely satisfying.

Anger needs justice – in proportion

Anger has a strange moral glamour. When you feel it, the world can seem suddenly obvious: someone has crossed a line, something has gone wrong, and your body is ready to answer. Medieval thinkers called this anger ira, and they took it seriously because it can point toward justice while also pulling reason out of your hands.

Consider that double nature. Some anger was seen as legitimate, especially when it appeared quickly in response to real harm and faded once the wrong had been addressed. No figure captures this better than Judith. Her city was under siege, its people were being starved of water, and the invading general Holofernes was using cruelty as strategy. Judith’s rage was therefore treated as morally defensible, even when medieval artists disagreed about how furious she should look while acting on it. Some images show her almost calm, others show violent intensity. Together, they ask a difficult question: How much anger can justice safely hold?

Sloth is the slow loss of care for life itself

Sloth is easy to misunderstand. The modern picture is usually laziness: staying still, avoiding effort, putting things off. Medieval thinkers meant something heavier by acedia. They saw it as a collapse of attachment, a state where the world still asks things of you, but your heart no longer answers with energy, pleasure, or trust.

That makes sloth unusually painful, because it can feel less like a choice than an invasion. Pride can be performed, envy can be aimed, and anger can be released. Acedia often arrives as numbness. You may know what matters, remember what used to move you, and still feel unable to act. Medieval writers described this condition through fear, bitterness, withdrawal, and despair – a pattern close enough to modern depression that it still feels recognizable.

Avarice occurs when objects start defining who you are

We often want things because they seem to promise a better version of ourselves. A jacket, a room, a phone, a house, a bank balance – each can shift from something you use to proof that your life has become impressive. Medieval thinkers called this avarice, and they understood it as excessive love directed toward material things, especially when the desire to acquire or keep them begins to take charge of you.

That fear made sense in medieval Europe, a period when trade expanded, banking developed, luxury goods circulated more widely, and money became a stronger social force. Writers such as Francis of Assisi responded with suspicion toward ownership itself. For him, possessions could subsume a person, making someone spend so much energy on surfaces that the self underneath grew weaker.

Gluttony isn’t just excess – it’s when food becomes fixation

Gluttony sounds like the simplest sin: too much food, too fast, with too little restraint. Medieval thinkers made it far more interesting. For Pope Gregory, gluttony could mean excess, eating before real hunger, intense craving, devotion to luxurious food, or a fussy demand that everything be exactly right. That means a person could fall into gluttony through overeating – but also through connoisseurship, purity rules, or anxious refusal. The common denominator here is fixation; food stops supporting life and starts occupying the center of the mind.

Thomas Aquinas sharpened this idea. His concern was not the menu itself, but the moment appetite outruns reason. You might eat too much, eat with frantic urgency, insist on rare delicacies, or become so delicate in your preferences that ordinary nourishment feels unacceptable. In each case, food gains too much power over thought. A meal should answer hunger and help you return to what matters. When taste becomes an organizing principle, you’re no longer simply enjoying food. You’re being managed by it.

Lust is only harmful when desire traps you inside fantasy

Lust, or luxuria, sits unusually close to love. Medieval writers treated it as the mildest of the seven sins because it begins with a force that can pull you toward another person, toward bodies, and even toward wonder. The danger comes when that pull narrows your world until a living person becomes an image you want to possess.

For Bernard of Clairvaux, desire could move in more than one direction. It could sink into fixation on bodies, where pleasure turns shallow and self-enclosed. Yet it could also rise toward devotion, service, and full attention to another life. That makes lust morally unstable. The same physical energy that can reduce someone to a surface can also become part of love, care, and even spiritual longing. The task is to steer desire outward, beyond your private appetite.
